IMPROVEMENT IN PEGGlNG-MACHlNES.

Specification forming part of Letters Patent No. 162,887, dated May 4,1875; application filed April 5, 1873.

To all whom it may concern:

Be it known that we, JOHN E. BIGKFORD, of Abington, county. of Plymouthand State of Massachusetts, and BENJAMIN F. STURTE- VANT, of Boston,county of Suffolk, State of Massachusetts, have invented certain new anduseful Improvements in a Machine for Making Pegged Shoes, of which thefollowing is a specification Our invention relates to an improvementinpegging-machines adapted to peg a boot or shoe resting on asupporting-arm, and without a last, the arm entering the shoe; and ourinvention consists in a shoe-supporting arm having a centralawl-receiving passage and a surrounding annular groove or awl-receivingpassage, so as to properly receive the awl in all positions of the arm.

Figure 1 is a front elevation of our invention, showing, in addition tothe same, a part of the ordinary pegging device. Fig. 2 is a sideelevation of the same, showing the supporting device in section. Fi 3 isa vertical section of the supporting and cutting-off device. Fig. 4 is aplan of the parts shown in Fig. 3. Figs. 5 and 6 show, in plan andsection, the end of the supporting-arm.

Let A, Fig. 1, represent a pegging device, which need not be describedin the specification, as it forms no part of our invention, and may beconstructed after any of the-approved methods. B is the feed-wheel;0,,the awl, and D the driver which forces the peg into the leather. E isa supporting-arm, formed as shown, and is arranged so as to swing freelyabout its vertical axis in the sliding bracket E The sliding bracket Eis attached by suitable ways to the frame K, Figs. 2 and 4, and isconnected to the weighted lever E Figs. 1 and 3, by a stud, E Fig. 3,the lever E being pivoted to the back of the frame Kin such a mannerthat the weight 111 Fig. 1, will havea tendency to throw up the slidingbracket'EH, and, consequently, the arm E. Thus the action of theweighted lever E is to hold the sole of the shoe which isnpon the arm Eagainst the feeding device B, and ready for the action of the pcgger.The head of the arm E is arranged as shown in Figs. 5 and 6; the hole Hbeing made vertical and in the axis of motion of the arm, so that itsposition is not changed by turning the arm. This arm is so located thatthe hole H is immediately under the peg-driver D, and this allows thepeg, as it'is driven, to pass freely through and project beyond theinner sole. The awl 0, being out of the center of the arm, strikes,after it has passed through the sole, into an annular groove, F, asshown in Figs. 5 and 6; and asthis annular groove is concentric with theaxis of motion of the arm, it is evident that the awl will always strikein it, whatever may be the position of the arm.

To cut off the peg after it is driven we use the following device: I isa knife, fastened to the holder 1, the upper end of the holder 1 beingconnected by a link, L, Fig. 3, to the arm, as shown, so that if theholder I is thrown forward it takes the knife 1 across the opening H,Figs. 5 and 6, at the same time elevating it slightly, so as to cut offthe peg close to the inner sole. This knife is operated by the system oflevers andlinks 1 I, I 1 and l, and the cam 1", as shown in Fig. 2. Thelink 1 of this system is in the center of motion of the arm, and isconnected to the bent lever l by a swivel-joint, M, so that any movementof the arm will not interfere with the action of the knife I.

We claim as our invention- In a machine for pegging boots and shoes, thesupporting-arm E, provided with the central opening H and the annularawl-receiving groove F, substantially as described.
